The hashtag derives from the well-known Irish song Trasna na dTonnta (across the waves) and is an initiative of the IrelandCanada University Foundation (ICUF) which is resourced by the Irish government's Third Level Education Overseas scheme which provides funding for the teaching of Irish in foreign universities.

The fund was set up to promote and encourage goodwill for the language outside Ireland and to provide a platform from which the language can be showcased as an international language.

Speaking ahead of this year’s event, government chief whip and Minister of State for the Irish Language Joe McHugh, said the campaign gives a “great insight” into the work being done to promote Irish worldwide and gives people the chance to make new connections online.

“My department is currently supporting the teaching of Irish in over 40 third-level colleges abroad and the demand for those courses is increasing year on year,” Mr McHugh said.

“The language is also experiencing a boom on social media, and #TrasnaNadTonnta gives more people the chance to take part in debates about the language online, and indeed to connect with Ireland, some of them for the first time.”

Last year people in 30 different countries engaged in the campaign and Mr McHugh said he hopes to see an increase in that number this year.

“Over the coming week, therefore, we urge as many people as possible, around the globe, to tweet in Irish and use the hashtag #TrasnanadTonnta”, he said.

The #TrasnanadTonnta drive comes just a week after the #nílsécgl campaign highlighting negative attitudes encountered by Irish speakers went viral.

The campaign started by writer and teacher Ciara Ní É prompted Irish speakers to describe negative attitudes they have encountered while speaking the language and reached almost 1m unique users worldwide.
